You notice that your new soft penis barely sticks out from your pubic hair. You feel tears rising as you look at this. Being mortified, you grab it with two fingers for the first time. It quickly stiffens, lengthening only half an inch. You will never be able to penetrate someone with that ... suddenly an electric jolt runs through your balls and your shaft. You pull your fingers away, your are surprised by your micro-dick's sensitivity.
A first contraction follows, even you no more touch yourself. Then a stronger one, which makes you understand that you are at the edge of cumming. And finally, a sudden orgasm erupts even though you barely touched your micropenis.
"What! How could it be?" you clench your teeth
You grab your little dick out of reflex. This does not prevent it from convulsing while spitting out numerous cum spreads. You can't do anything but endure and grumble. Cum drips through your fingers and falls to the floor.
Once the orgasm is over, you unclench your teeth and say:
"What just happened??"
